BIT FIELD TYPE DEFAULT DESCRIPTION

7-0 ODT R/W 0

This bit adds a time offset to the overdrive portion of the library

waveforms. Some motors require more overdrive time than others, so this

waveforms. The maximum voltage value in the library waveform is

automatically determined to be the overdrive portion. This register is only

useful in open-loop mode. Overdrive is automatic for closed-loop mode.

The offset is interpreted as 2s complement, so the time offset may be

positive or negative.

Overdrive Time Offset (ms) = ODT[7:0] × PLAYBACK_INTERVAL

See the Control5 (Address: 0x1F) section for PLAYBACK_INTERVAL

details.

BIT FIELD TYPE DEFAULT DESCRIPTION

7-0 SPT R/W 0

This bit adds a time offset to the positive sustain portion of the library

waveforms. Some motors have a faster or slower response time than

others, so this register allows the user to add or remove positive sustain

time from the library waveforms. Any positive voltage value other than the

overdrive portion is considered as a sustain positive value. The offset is

interpreted as 2s complement, so the time offset can positive or negative.

Sustain-Time Positive Offset (ms) = SPT[7:0] ×
